Pro Baseball Players Spot 101 mph Fastballs with this…

Orange ‘Eyesight Nutrient’

The Same ‘Eyesight Nutrient’ that Over 20,000 American Men & Women Have Now Used to Improve Their Own Near-Distance, Far-Distance, and Night-Time Vision.

From the Desk of

Dr. Ryan Shelton

These lucky folks are more comfortable enjoying a good book or seeing their phone up close…

They’re more clearly seeing faces and expressions from across the room, so they feel more connected to their families, and more a part of conversations…

And they’re more confident when they drive after dark.

All thanks to this orange eyesight nutrient that pro baseball teams have used for years.

In fact, the 3 teams who first adopted this nutrient – Boston, Cleveland, and Chicago – scored over 20% more runs per season, and their pitchers threw 34% more strikeouts.

They even won the World Series 3 out of 6 years!

So it’s no surprise that their eyesight nutrient also works for regular folks.

Because For Pro Baseball Players, Their Vision Can’t Just Be Good Enough.”

They have to spot fly balls a hundred feet in the air, against the glare of the afternoon sun.

They have to track the spin on a pitch thrown twice as fast as highway speed limits.

“Hitters have three tenths of a second on a 90 mph pitch to make a decision,” says Keith Smithson, the Nationals’ team optometrist.

If you want to play in the major leagues, you need the best vision.

As Sports Illustrated explains: “That's why MLB players have begun taking a unique nutrient to boost their eyesight.”

2nd Baseman for the Miami Marlins, Neal Walker says: “After taking it every day, I felt like I could see details better and I wasn’t squinting as much. It was like internal sunglasses.”

And Unlike Other Health Programs, Where an Athlete Might Only See Results after Several Months…

The Difference in Vision Can Show Up Surprisingly quick!

This orange ‘Eyesight Nutrient’ is professional baseball’s secret weapon to perfect and protect the eyesight of their players, from the youngest rookie, to the most seasoned 20‑year veteran.

I’m Doctor Ryan Shelton, and while I love watching baseball with my kids, I’m not a major league outfielder, and neither are my patients.

But here’s the exciting part —

This Pro Baseball ‘Eyesight Nutrient’ Has Now Leaked to the Public…

Regular folks all over the country are using this baseball vision secret to protect their own eyesight.

And Since 2018, I’ve Used This Secret Myself to Help Over 20,000 Men and Women Protect Against Eyesight Frustrations like…

Struggling to read books, or recipes, or their phones, because their near-distance vision is slipping

Squinting and straining to read road signs, or recognize a face from far away because their far-distance vision is slipping…

Losing the freedom to drive at night, or wondering why the TV seems dim, because their low-light vision is slipping…

Vision decline interrupts lives everywhere.

But with this Orange Eyesight Nutrient…

These 20,000 Men and Women Have Rescued Their Declining Eyesight, Stayed Connected with the World, and Kept Their Independence

And you don’t need a pro athlete’s salary to afford this nutrient.

In fact, my recommended source is…

An Orange Autumn Flower that Grows Wild in at Least 34 States

The ‘Eyesight Nutrient’ inside has been tested and proven by nutrition researchers.

Harvard Medical School reported that men and women who get more of this nutrient in their diets have a “long-term reduced risk” of vision decline.

In 2012, the Vision Sciences Laboratory at the University of Georgia reported that this unique nutrient helps you…

See close-up images more clearly, like prescription bottles or your cell phone

See further distances, so you can be waving at friends before they even notice you

Reduce glare & eye strain, so computer screens or bright sunlight aren’t so tiring on your eyes, and…

Enhance your ability to see details in low light, like when driving at night.

And those results were confirmed…

In 2013, by a scientific study published in the renowned medical journal Nutrition…

In 2014, by researchers in Tokyo at the Kono Medical Clinic…

In 2017, by the College of Pharmaceutical Engineering in China

And in dozens of other studies, verifying their results with thousands of patients.

This Nutrient was even featured on programs like Dr. Oz, and health segments from CNN and Fox News.

And I’ve Seen The Power of This Orange Flower’s Nutrient in The People I’ve Already Helped…

"I had trouble seeing at night and I squinted in the daytime. Now I can actually read without using glasses! It's really working. I like it a lot."

"I couldn't believe I started feeling a difference in a matter of days. My eyesight is much sharper than it was. When I get up in the morning, I forget to put my glasses on because I'm seeing so well!"

This is bringing me closer to not needing any reading glasses after only a month! My eyes are healthier and aren't feeling as tired.

“I did notice a difference when I was not wearing my glasses at night, driving home, I could see road signs a little clearer, so it did help me. I have a very light prescription so I was able to not have my glasses on and things were not as fuzzy, I could make it out.”

“Within about two weeks I kinda started noticing improvement. I’m really impressed. I feel a little better driving at night time. Other car lights don’t really bother me. I can see the lines on the road a lot easier.”

“I’ve never taken anything for vision before, so I really noticed a difference in the clarity.”

“After about seven days, I noticed a difference. I was quite impressed. I highly recommend other people to give it a try.”

“Before I found this, I couldn’t do anything without my eyeglasses. Since I started, I hardly use my glasses now. I can read, sew, or do chores without them. My vision is much clearer!”

“Running my wife to the airport last night, my eyes did better than usual against the glare from headlights on the wet road. This has helped my night vision, particularly on the road.”

“I have experienced better overall vision. I no longer wear my glasses as much.”

“I can finally read the computer screen without any glasses.”

“My optometrist was rather surprised at my improved vision.”

“I have more confidence driving.”

“I can read my books more easily.”

“I can see road signs more clearly.”

Those are only a few of the over 20,000 men & women who have experienced the vision-boosting power of this orange autumn flower so far.

Now, you might say, “my eyesight’s not that bad yet.”

But the National Eye Institute reports that age-related vision decline happens to everyone.

Small warning signs now can mean devastating problems around the corner. Problems that could leave you isolated and steal your independence.

If the secret of Professional Baseball’s orange eyesight nutrient caught your attention, then…

I’m going to assume that your vision health has been worrying you more and more lately.

Like when it’s a gray, rainy evening. The sun is setting fast, but you still have errands to run. You’re standing at the front door, car keys in hand.

You worry: Is it safe to drive? Will you see road signs clearly enough? Will you see hazards in the street?

Your stress only gets worse when your spouse or child asks, “are you sure you’re okay to drive at night?”

Or there’s the simple frustration of being with a group of family or friends. You can hear the conversation just fine, but you miss the small facial expressions of the people farthest away.

You miss what everyone’s laughing at, because you couldn’t see it. You don’t feel the same connection to the group that you used to.

Or when you’re at work, and you fumble with your reading glasses or bifocals, or have to squint your eyes to read something.

Your younger coworkers notice, and the hairs on the back of your neck stand up as they whisper about whether you’re getting too old to do your job.

Then there’s the annoyances that might look like no big deal to other people.

Words get blurrier. You can’t read books with your grandkids in your lap like you used to.

Or the TV looks so much darker. In dark scenes of your favorite show, you have no idea what’s going on.

Even your own children may start to treat you like you’re fragile. There’s doubt in their eyes about how much longer you’ll be able to take care of yourself.

After all, declining eyesight is one of the biggest signs of old age. Think about it, when kids play pretend and act elderly, the first thing they do is lean in and squint!

It’s frustrating when loved ones don’t understand…

You still have a role to play and a life to live.

And That Is Why I Want to Help You.

In my medical career, I’ve devoted myself to helping men and women continue to reach their goals and live their dreams.

My health courses and books have helped millions of people.

And with my face-to-face work with patients…

I’ve found success through solutions that are both natural AND backed by research, like this orange eyesight nutrient used by pro baseball players.

Right now, I’d like to help you enjoy a life with fewer embarrassing and isolating worries like declining vision.

Dr. Ryan Shelton

Forgive me for what I’m about to say, but it’s the painful truth…

If you let it, declining vision will hold you back and leave you in the dark…

It will rob you of respect at work…

It will make your family think they have to take care of you, even though you’ve been taking care of them for decades…

It will trap you at home, unable to drive, or even experience the world for yourself…

But ONLY IF you don’t protect yourself.

If you do protect yourself, then when your errands get pushed back until dark, and you’re standing in the doorway with car keys in hand…

You’ll be more confident that you can hit the road and get things done.

And you’ll have a happier time in large groups of family and friends, since you can see everybody’s face, and follow the joking and laughter.

So how do you get these moments back?

Especially considering that…

Your eyes could be aging faster than you realize…

Because between age 40 and age 60, your risk of serious vision concerns increases by 265%!

And time passes in the blink of an eye. Before you know it, your eyesight could be nearly three times worse!

What’s really scary is that the New England Journal of Medicine published a study that shows…

People With Vision Issues Are 17x More Likely to End Up in a Nursing Home!3 4

So don’t think that your vision decline will magically “pause.” The fact is, it gets worse for everyone.

It gets worse for everyone.

Think about it: have you ever gone to the optometrist and they lowered your prescription?

Of course not!

Because common eyesight solutions don’t do a thing to protect your eyes.

As your vision gets worse, most doctors prescribe reading glasses or bifocals.

But it’s tough to keep the respect of your coworkers when you have to pull out your reading glasses to see a manual.

It breaks your heart to wonder if your own children see you as a burden.

It’s downright scary to consider whether it’ll ever be safe again for you to drive at night.

And here’s the thing: glasses don’t protect your damaged lens or retina. All they do is bend the light before it comes into your eye.

Even with glasses, your vision will just keep getting worse.

Some people think laser eye surgery will save them. But laser surgery doesn’t help with age-related vision issues.

It can’t save you from the sort of eyesight decline we’re talking about.

The most frustrating part is that while you’re feeling trapped by declining eyesight…

The world of medicine acts like age-related vision decline is 100% natural, and that you and I should roll over and accept going blind.

But just because vision decline happens to everybody, doesn’t mean it’s natural.

After all, over 70% of Americans are overweight, but that doesn’t mean it’s normal or healthy.

So why should we consider declining eyesight “normal?”

Dr. Ivan Schwab, a professor of ophthalmology at the University of California, Davis said that “the rates of myopia [nearsightedness] have skyrocketed over the past 300 years.”

So the truth is, today’s near-universal rates of vision decline might NOT be normal.

Believe it or not, I’m going to call that good news.

Because now that we’ve identified that there is actually a problem…

We can solve it.

Fortunately, there is a way to protect your eyes, and get back those happy, confident moments, like enjoying a breathtaking mountain view, or giving your son advice and feeling how much he still respects you.

Let’s talk about how to get you there.

First things first, you’ve got to understand…

Here’s how your eyes should work.

It’s surprisingly simple:

1. Light comes in through your lens…

2. Then projects the image onto your retina (the inside back of your eye)…

3. The image then travels along your optic nerve to your brain.

Your lens flexes and adjusts to focus the image.

It stays loose to focus on objects far away, and flexes tight to focus on close objects.5

If your near-distance vision is getting worse as you age, here’s what’s happening:

Your lens is losing its ability to flex and focus on close objects.


Right this second, while you’re reading this letter, you’re getting attacked by a damaging kind of oxygen called “Reactive Oxygenated Species,” or…

ROS Toxins

As you age, they invade your eyes more and more. With each passing day, these toxins brutally attack your lens cells, making them stiff and inflexible, and making you need embarrassing reading glasses or bifocals.6

It’s like leaving a piece of leather in the sun too long.

It becomes wrinkled, tight, and brittle.

That’s what ROS Toxins do to your eyes.

If you don’t protect yourself, your lens will get stiffer and stiffer, until your vision decline makes you dependent on charity just to live!

As if that weren’t enough…

ROS Toxins are also responsible for declining far‑distance vision and low-light vision. They cloud your lens cells, making all the light that passes through them darker, so the world is more difficult to make out.5

And here’s the most terrifying part:

ROS Toxins cause damage that’s linked to serious vision concerns.6

Various studies have found links between oxidative damage and the sort of vision issues that leave you totally isolated.

So you must protect yourself.

Whether you’re worried about your near-distance, far-distance, or low-light vision, the underlying problem is this assault by ROS Toxins leaving your eye’s lens cells stiff and cloudy.

Let’s talk about how to protect yourself against these toxins, and get back those happy family moments that require clearer eyesight.

The next step is to understand:

Where Are These ROS Toxins Coming From?

Why are there more as you age?

The answer scared me:

ROS Toxins are found everywhere in today’s environment: Plastic containers, processed food, and chemicals in our water.8

There’s really no avoiding them.

But there’s a shocking, deadlier source of ROS Toxins most people don’t know about:

Invisible Blue Radiation

Invisible Blue Radiation

Also known as Blue UV Light.

If you’ve heard of the dangers of Blue UV Light before, the problem is likely even more urgent than you think.

When this radiation hits your eyes, it triggers a chemical reaction that releases a swarm of ROS Toxins.9

And there’s virtually no escaping it.

Today’s modern world is packed full of sources of Blue Radiation.

Every time you answer your smartphone, or get on the computer to check your email, or even just flip on the TV, those screens assault your eyes with Blue Radiation.

And you know those “eco-friendly” LED light bulbs? They’re another dangerous source of this blue UV light.

Even the credit card machine screens in the checkout line aren’t safe.

Even the sun emits this damaging blue UV light.

That’s why Blue Radiation is such a threat to the eyesight of every American man and woman over 45… it overloads your fragile lens with vision-destroying ROS Toxins, and there’s no way to escape it!

Your lens cells get stiff and clouded, and you start to lose your biggest connection with the world: your eyesight.

So what can you do?

Even if you throw out all of your electronic screens, and never set foot in a store with LED light bulbs, you can hardly avoid sunlight.

As a doctor, this worried me. I was powerless to stop the constant assault on my patients’ vision.

The truth is

While You Can’t Escape the Constant Blue Radiation & ROS Toxin Assault on Your Eyes…

You CAN Shield Yourself Against It…

And You CAN Allow Your Body to Heal!

And in fact, Your Body Already Has a Natural Shield Against ROS Toxins.

Your eye cells protect themselves with natural compounds that I call…

Vision Detoxifiers.

Your body produces plenty of these when you’re young, but once you pass 40, you produce fewer and fewer.

But this is actually good news, because it’s such a simple problem.

Your eye’s Vision Detoxifiers SHOULD be protecting against ROS Toxins, but you don’t have enough of them anymore.

So to support against weakening eyesight… all you have to do is support your levels of Vision Detoxifiers.

What are these Vision Detoxifiers?

They’re a special type of antioxidant that are essential to your eyesight health.

But I’m not talking about carrots or simple Beta Carotene you’d get at Walmart.

You see, when I first set out to find a solution to ROS Toxins stiffening and blurring the eye’s lens, I wasn’t looking for a temporary, band-aid fix.

I wanted to help my patients find a natural solution, backed by real research.

I was determined to help them show the world that they’re NOT any less than they used to be. To help them get back those happy moments of sitting around with your family, and seeing clearly their smiling faces as they tell jokes and laugh at old family stories.

My search was discouraging at first, since mainstream vision health only talks about glasses and surgery, but if you look at the cutting edge of research, there’s hope.

Because buried deep in a medical journal, I found the answer.

I discovered an orange Autumn flower that contains 2 key Vision Detoxifiers.10

These key nutrients support your body’s natural supply of Vision Detoxifiers.

These compounds dissolve the damaging ROS Toxins, and they support your lens’s natural ability to heal itself.11

Even though I read about these detoxifiers helping people’s eyesight, I was still cautious.

I didn’t want to get excited until I was 100% sure that the research confirms that these two nutrients had a real impact on eyesight.

Imagine my smile when the more I read, the more evidence I found:

These two compounds are what I call the Color Essence of nature.

They’re the molecules that give this flower its orange and golden colors.

They’re a class of nutrients called a Carotenoid.

If you’ve heard the word “Carotenoid” before, it’s because they’re nutrients that support vision health. Some of the more common ones come from carrots. That’s where you get the common wisdom that carrots support vision health.

But – and this is VITAL…

The carotenoids you need to protect your lens are NOT the common carotenoids that everyone has heard of.

These are recently discovered, and it’s possible your family doctor and optometrist don’t even know much about them.

The first vital Carotenoid you need is called Lutein

The second is called Zeaxanthin.

These are rare carotenoids and Vision Detoxifier Compounds.

According to a 2017 study published in the medical journal Molecules, their molecular structure is perfectly designed to dissolve ROS Toxins.

It’s like touching a needle to a bubble. When Lutein and Zeaxanthin make contact with ROS Toxins, they burst those toxins apart. Your body absorbs what’s left, and your lens stays safe.11

So Lutein and Zeaxanthin help maintain the clarity and flexibility of your lens.

They protect your near-distance vision, your far-distance vision, and your night-vision.11

Like I mentioned, Lutein and Zeaxanthin are the “Color Essence” of many flowers.

They’re even found in Dandelions.

You can add Dandelion greens to a salad as a quick way to get these nutrients.

But let’s face it… most people hate the taste of Dandelion greens.

More important, though, is that there’s not enough of these detoxifiers in dandelions to provide a strong defense against ROS Toxins.

Fortunately, I found a more potent source of Lutein and Zeaxanthin, from a more vibrant flower…

The Marigold.

Marigolds are a common sight in flower gardens, and when planted in vegetable gardens, they protect other plants from toxins to help them grow stronger!

It’s that protective ability that we’re interested in…

Because marigolds are the most potent source of these two vital Vision Detoxifiers.10 11

The top nutrition researchers from India, Italy, Poland, Turkey, Iran, and England all came together to report that…

Marigolds are a shield against ROS Toxins, and help you support your vision.10

And the results of this protection are amazing…

In placebo-controlled research at the University of Georgia, doctors gave 30 men and women marigold extract. The results? The patients were able to see fine details better, and make out details more clearly at night.

In other research, marigold extract helped men and women be less affected by glaring light, and helped their eyes adjust quicker to changes in light.

Then there were the studies that showed marigolds helped people’s eyes filter out blue UV light.

And they helped ease eye strain so people’s eyes felt less tired.

When I discovered this, I was thrilled.

I’d finally found the answer to help my patients reclaim their confidence to drive at night, and enjoy more moments like looking out at a pretty landscape with their family.

But There Was One Big Problem:

Your body doesn’t naturally absorb Lutein or Zeaxanthin very well.

Doctors at the University of Connecticut discovered that, taken by themselves, have very little impact on your body’s actual levels of these nutrients in your body.12

By themselves, they have a minimal effect on eyesight.

I was frustrated.

I’d discovered the cause of today’s abnormal amounts of vision decline: the epidemic of Blue Radiation, which allows ROS Toxins to stiffen and blur your eye’s lens.

I’d found the most effective Vision Detoxifiers to shield your lens.

I’d found the most potent source of these detoxifiers.

But for some reason, the human body wouldn’t absorb them!

I felt like banging my head against a wall!

Until one night, I was rereading a study from the University of Connecticut about Carotenoid absorption. (Remember, Lutein & Zeaxanthin are Carotenoids.)12

The study found that…

Vision Detoxifying Compounds are better absorbed by your body when accompanied by Zinc.

In other words, you need Zinc for these Vision Detoxifiers to protect your eyesight.

When I looked closer at the University of Georgia research on marigold extract, I found that they’d also given zinc to their patients. That’s how they saw such great results!

Zinc is a simple mineral that your body uses for everything from hormone balancing to skin health.

And when you pair Zinc with Carotenoids like Lutein & Zeaxanthin, your body absorbs them better, and uses them to dissolve ROS Toxins and support vision health.

This combination protects you against vision decline, to help you keep living your life.

Here’s the catch…

Swiss Nutrition Researchers discovered that for maximum absorption, the zinc must be the right type, and the right amount.

Unfortunately, that precise amount is almost impossible to figure out on your own.

Going to the health food store and buying Marigold extract and a Zinc supplement won’t do it. You need the exact ratio of Zinc to Lutein & Zeaxanthin, or your body won’t absorb it properly.

Once I’d discovered this, the solution to vision decline was finally in sight.

We spent months researching and testing until we had…

The precise blend of Lutein & Zeaxanthin to support your healthy vision… and the exact amount of Zinc to help your body absorb them for maximum vision support.

I worked with my team at Zenith Labs® to condense it into easy-to-take capsules. We decided to call it…

Vision 20®

Vision 20® is the easiest way to boost your levels of Vision Detoxifiers, shield yourself against ROS Toxins from Blue UV Light, and support the flexibility and clarity of your lens cells.

It helps protect your near-distance vision, so you relax with a good book, or use an ATM without hunching over to see the screen.

It helps protect your far-distance vision, so you can confidently recognize friends from far away, and read road signs.

It helps protect your low-light vision, so you can continue to drive at night, and so you can navigate your home in the evenings.

Vision 20® is the secret to regaining confidence about your vision. To holding on to your independence, even as you age.

To keeping the respect of your family, so they still see you as someone to look up to, and not as a someone weak and in need of care.

That’s exactly what happened with Maurice Ngai, age 53, who used Vision 20® to support his own vision, and then reported:

“I believe it works so I suggested my wife and two gals who also have different degrees of short-sightedness take Vision 20®, too. Four of us each take it every day now. The best thing about Vision 20® is that the deterioration of vision stops!”

Maurice was able to go from losing his eyesight and becoming a burden on his family… to restoring his vision AND helping his wife and friends!

That’s the Miracle of Vision 20®

Not just supporting your vision health, but supporting you in your role as a mother, father, protector, provider, coworker, and however else you help those around you.

I know how important it is to you to protect your vision and your ability to help others, so I decided to give you an extra boost.

Vision 20® Starts Out with the Highest-Quality Lutein & Zeaxanthin Available Today.

Here at Zenith Labs®, we deliver only the purest nature-based solutions. So Vision 20® includes a special form of these carotenoids.

It’s called LuteMax 2020.

It’s a marigold extract. That means it’s all-natural lutein and zeaxanthin. Nothing synthetic, nothing added.

And it delivers these carotenoids at the same ratio as found in natural diets.

Because the goal of Vision 20® is NOT to pump you full of this or that nutrient…

It’s to make it easier to naturally get the nutrients you’d get if you had your own private natural chef.

The ratio of lutein to zeaxanthin that you get in Vision 20® is the same ratio you’d get if you started eating marigold blooms or dandelion greens with every meal.

You’re getting nature’s vision support.

Another reason that Lutemax 2020 is the best way to get lutein and zeaxanthin is that it’s the most researched version of these carotenoids.

According to the extensive research on LuteMax 2020, here are a few ways that it’s been shown to help:

It’s a natural filter of Blue Radiation. This protects your eyes in everyday surroundings, including sunlight, indoor lighting, and most digital screens.

It supports your ability to see objects clearly and crisply, up close or far away.

It improves vision in fine-detail situations like needlepoint or reading in low light.

It helps support vision in poor light by increasing retinal sensitivity.

It significantly improves glare tolerance - the recovery time for seeing clearly again after being temporarily blinded by bright light.

It promotes healthy eye function against high energy light from computers, smart phones, TV and outdoor light in 12 weeks.

And it helps to relieve tired, strained eyes.

That’s why we include LuteMax inside Vision 20®. With this specific marigold extract, with lutein and zeaxanthin at these specific ratios…

The Research Shows Powerful Results.

But remember…

Absorption is even stronger when you add zinc. So in addition to the LuteMax version of lutein and zeaxanthin…

We also include 50mg of Zinc.

Zinc Citrate

We deliver it through zinc citrate, which contains more pure zinc than other supplements.

If you look on the bottle for most zinc supplements, you’ll see that it’s labeled zinc sulfate, or zinc gluconate. Zinc citrate contains 300% the elemental zinc of those old versions.

Again, our goal here is to recreate the nutrients you’d get from simply eating the right foods.

Zinc citrate is the closest to getting zinc from foods like beef or nuts.

That’s why Vision 20® is like adding nutrient rich foods to your diet, to give you natural amounts and ratios of lutein, zeaxanthin, and zinc.

And after these 3 core ingredients, we also decided to include an additional blend of vision-supporting nutrients.

We started with two more carotenoids…

Lycopene & Astaxanthin

Lycopene is what makes tomatoes red.

Like lutein and zeaxanthin, Lycopene protects your eyes from ROS toxins.

A study presented at the Conference on Natural Vision Improvement found that people who ate high levels of Lycopene had the lowest rates of vision issues.

And low levels of Lycopene were linked to increased risk of vision issues.15

Then in 2016, the Brazilian Journal of Ophthalmology reported that Lycopene helps reduce oxidative stress like ROS Toxins.16

Astaxanthin comes from fish and shrimp, and it’s what gives them their pink color. Like the other carotenoids, the research shows that Astaxanthin supports healthy eyesight.

Then after these two extra carotenoids, we included…

Bilberry Fruit Powder

Bilberries are a close cousin to the Blueberry. British Air Force pilots ate them in WW2 to improve their night vision and help them shoot down Nazi bombers.

The Journal of Science, Food, and Agriculture found that taking Bilberry Extract helped people prevent DNA damage, and reduce their levels of ROS Toxins.23 24

And finally, we round it all off with two final vision boosters:

Ginkgo Biloba & Maritime Pine Bark Extract

The research shows that adding these to your diet supports low light and distance vision.20

As we completed the formula for Vision 20®, we knew we’d found something unique…

A nutritional supplement that mimics the doses and ratios of adding these foods to your diet.

The foundation is the LuteMax 2020 and Zinc citrate.

And it’s rounded out with the two additional carotenoids, and three extra vision boosters.

When we first shared Vision 20® with the Zenith Labs® family, we knew it would change lives.

But even we were surprised at the overwhelming response.

Just ask Carolina D., age 73, who wrote me to say:

“Before using Vision 20®, I couldn’t do anything without my eyeglasses. Since I’ve started taking it, I hardly ever use my glasses anymore. Most importantly, I can read, sew, or do other chores much longer without them. My vision is much clearer now. I will undoubtedly recommend Vision 20® to my friends. It fulfilled the life and eye health I had been wishing for for a long time.”

I was floored by what Brittany had to say:

"My eye health has always been a bit poor. Since the age of about 10, I've worn glasses and they'd gotten thicker every time I got a new pair! I recently had Lasik surgery done but my eyes were still blurry at night for about 4-5 months after the procedure. I tried using Vision 20®and it actually works! I am able to see way better at night than before. No more fuzzy lights. I have sharper eyes during day & night. My vision is back to 20/20."

And imagine how thrilled I was to hear from airplane pilot Bernard Blair, age 62:

“Prior to starting Vision 20®, my eyes seemed strained and not as clear. I had to get corrective lenses to 20/30 far-sighted vision. This is required by the FAA as I am a pilot. Yes, the prescription lenses made a difference, but my eyes still were not as clear until I started using Vision 20®.

“After the first bottle, I began to see much clearer, day to night. I had to admit to myself: this product really does work. My vision was getting more clear and I could see objects with normal sharpness and definition, long and short range. My night vision began to improve as well. I would highly recommend Vision 20® to anyone.”

All these stories of change and confidence are why I truly believe so many men and women can benefit from Vision 20®

The lutein & zeaxanthin, and the accompanying carotenoid blends, really can rejuvenate your eyesight.

You’ve seen the research from Harvard Medical School, and top clinics around the world.

And now you’ve heard the stories of men and women who’ve tried and loved Vision 20®, after they were in the exact same spot as you.

They paid close attention to this presentation, and then they wondered:

How Do I Get My Own Supply of Vision 20® Right Away?

And also, how much should I take each day for best results?

Now, I’ve seen Vision 20® help so many people, so I wish it were easy to produce and send out.

But the cold truth is, it’s tough to keep our stockroom shelves full…

And there are three reasons why:

Number 1 is simple: Vision 20® is one of Zenith Labs®’ most popular health supplements.

Most customers buy a 6-month supply at a time, then they come back six months later and do it again. So we’re always sending out orders that are filled to the brim.

The second reason it’s difficult to keep our stockroom full is because…

We Lead the Industry in Delivering Pure, Quality Products

Vision 20® is certified non-GMO and Guaranteed Pure.

The bottles are certified BPA-free, and for anyone concerned about allergies, Vision 20® is also gluten-free. That may only be a handful of our customers, but we don’t want to leave anyone behind.

And this is Zenith Labs® we’re talking about, trusted by customers all around the world, and well-known for obsessing over the pristine quality of each and every capsule we manufacture.

Like all our products, we manufacture Vision 20® in a GMP facility that’s been certified by the NSF for sanitation and quality, and that’s regularly audited by the FDA for potency.

In other words, while other supplement manufacturers may skirt regulations, even giving you watered-down or tainted carotenoids to save money…

Zenith Labs® guarantees pure, eyesight-boosting lutein & zeaxanthin, because our quality control is even stricter than government regulations.

But even that’s not enough for us.

We also make sure each source of ingredients is closely audited, to guarantee every element of Vision 20® is perfectly pure in order to revitalize your vision, your confidence, and your independence.

And then on top of all that, we individually test ingredients throughout production.

Every step of the way, we’re making sure that Vision 20® contains exactly what it says on the label.

We dip into our own profits to deliver a top-notch product.

We may not make as much money today, but we know you’ll be a Zenith Labs® customer for life.

All these strict quality-control measures go above and beyond most companies, and that means our farm-to-bottle process takes a lot longer.

Any slowdown at any step of the process can mean our stockrooms go dry.

And the third reason why it’s more difficult than I’d like for you to claim your own supply of Vision 20® is that…

The premium form of lutein & zeaxanthin that we use is in high demand

Like I mentioned, we get our lutein and zeaxanthin from marigold extract. That’s the source of these carotenoids that’s most easily absorbed by your body.

But do you know what else marigolds are used for?

They’re used as a natural remedy for everything from infant diaper rashes, to protecting sensitive skin, to helping with varicose veins.

If you look up marigolds’ scientific name, calendula officinalis, you’ll see that they’re used in medicines for upset stomachs or digestive issues. And the bright colors of the flower mean that it’s highly sought after by ecologically-conscious clothing and textile companies – it can be made into all-natural red, yellow, or orange dyes. And then of course, everybody from flower shops to wedding planners wants to order marigolds simply because of how colorful and beautiful they are.

This high demand for marigolds means that sometimes our suppliers run out.

We only work with farms that have strict natural growing methods, and this means we’re at their mercy. If they run out of this years’ harvest because all these other industries placed big orders before we could… sometimes we have to wait for the next harvest to get the lutein and zeaxanthin we need to make our next batch of Vision 20®.

So it’s common for us to run out of Vision 20®, and then have to wait for our delicate farm-to-bottle process to slowly restart.

Sometimes it’s quick to refill our stocks… but sometimes our customers have to wait months.

But if you see the checkout button on this page, that means we at least have a temporary supply right now.

And with all that being said…

I hate to imagine anyone continuing to suffer from the loss of hope and independence that you get with vision decline.

Especially when there’s such a simple, natural solution to protect your eyes from ROS toxins in order to strengthen and clear your eye’s lens.

Which is why I’d like to share with you exactly how to get your own supply of Vision 20® today.

And before I show you that, let me return to that second question from before:

How much Vision 20® should I take each day?

It’s as simple as you’d think: just take one capsule each morning…

But here’s the vital part:

Make sure to take it every day for at least 30 days.

Here’s why it’s important not to miss even a single day in that first month:

Of course, the carotenoids in Vision 20® get to work right away. But while the benefits may start to work on a molecular level from Day 1…

The longer you use Vision 20®, the more you’ll notice the changes to your eyesight.

Just ask Kay Hendricks, who said:

“I have been using Vision 20® for several months and recently I can see the computer screen without reading glasses. I can see the TV better and my distance vision is clearer.”

Also keep in mind that those studies we discussed from the Kono Medical Clinic in Tokyo tested results after using lutein & zeaxanthin for a full 30 days.

The study from the medical journal Nutrition even tracked improvement every 30 days for a whole year! And while improvement happened quickly… it also kept getting better over time.

After all, we’re not talking about any magical eyesight potions. We’re just talking about protecting your eyes from ROS toxins, and helping your body get back to work strengthening your vision. Once these systems are protected again, you can start to see some results quickly, and then feel stronger and stronger results with each passing week.

So it’s vital that you take Vision 20® for a minimum of 30 days.

That’s why I personally recommend that you claim at the very least a 3‑month supply of Vision 20®

Or if you’re very determined to enjoy real change in your eyesight…

Claim the complete 6-month supply.

That will give you the strongest, most guaranteed results, and support your healthy vision that will keep you active, comfortable, and independent.

Now, let me say again that Vision 20® is only available on this website, and for the reasons I just shared with you…

Our stocks will run dry before long.

Especially with how much our farmers and manufacturers struggle to keep up with the extreme demand for marigold extract.

And let’s talk about that high demand.

Obviously, the simple law of supply and demand says that:

Because marigold extract is so popular and so tricky to get your hands on, the price should be high to match that low supply and high demand.

And normally, Vision 20® would be one of Zenith Labs®’ pricier products, with the regular retail value being $79 per bottle.

That regular price makes sense, especially when you consider how much easier Vision 20® fits into your life than other vision solutions.

You can pay a thousand dollars for laser surgery… and risk dry, itchy eyes for the rest of your life. And that’s if laser surgery will even work for your specific vision concerns. (If you’re mostly worried about age-related vision problems, laser surgery can’t help you anyways).

Or you can wear thicker and thicker lenses until you feel like you’re wearing fishbowls on your face – and either wear bifocals or carry two pairs of glasses. But again, many folks reach a point in vision decline where even glasses don’t help much anymore.

Even other nutrient supplements can’t live up to Vision 20®, since they just throw one or two of the most common ingredients at you. Not to mention they usually leave out Zinc, which your body needs to properly absorb carotenoids.

Or if you decided to buy all of the Vision 20® ingredients separately, it would cost nearly $200.

Beta Carotene 2799

Zinc 1400

Taurine 1495

Bilberry Extract 2550

Lutein 1804

Lycopene 2495

Retinyl Palmitate 1527

Rose Hips 1100

Grape Seed Extract 3399

Zeaxanthin 1349

Plus, keep in mind this letter I received from Ernest Barry, age 74:

“Through my use of Vision 20®, my recent visit to the optometrist found that my vision had improved. The improved sight is a blessing, and not needing updated lenses offsets the cost of the capsules.”

When you consider all that, $79 for Vision 20® is really a good deal…

Plus, there’s the impact to daily life that money can’t buy…

The independence you maintain from continuing to safely drive at night…

More easily seeing the TV – even reading the news ticker on the bottom of the screen…

Reading your phone, or a prescription bottle, or a good book without exhausting eye strain…

More respect from your coworkers, friends, and family, since with strong vision, they won’t be so quick to see you as “old”…

And the relief of finally feeling like you’ve seized control of your declining vision… and excitement that you’ve got a happy, active life still ahead of you.

When you consider all this together, the low price of $79 is practically a free gift with a curly ribbon on top.

Even still, you won’t pay anywhere close to $79 for a 1-month supply of Vision 20® today.

Because like I shared earlier…

I’ve seen how vision decline can lead you to loneliness and damage your self-confidence…

So I want to help as many people as possible.

That’s our whole philosophy here at Zenith Labs®.

Which is why when you order right now, you can get your own Vision 20® for a one-time investment of just $59 per bottle.

That’s a 1-month supply.

But let me show you an even better price.

I understand that most people want to enjoy the benefits of Vision 20® for years to come…

And the hard truth is: our supplies are very limited.

So I completely understand that they want to stock up on a full 6‑months’ supply.

Small actions now will have a massive impact on your life in the coming months, years, and even decades.

I’ve noticed that what sets successful, happy people apart, is that they make decisions that help them avoid future problems, and that help them enjoy a healthy, successful everyday life.

This small decision to claim your supply of Vision 20® will help you avoid the frustration and isolation of declining vision…

And it’ll help your body protect against and heal from ROS toxin damage, to strengthen your near-distance, far-distance, and low-light vision.

Those who choose the 3-month supply want to make sure they can keep taking Vision 20® without interruption.

Not only are you serious about your health and happiness, but you’re responsible enough to want to be absolutely sure that you make the right choice for your situation.

I’ve already shown you the dozens of medical studies that back up everything I’ve shared with you today.

And you’ve heard some of the great experiences customers have already enjoyed with Vision 20®.

So let me share one more thing with you:

And prove for yourself that you can enjoy the same experiences as the happy customers you already heard from…

I’m talking about people like Frank Hansel, who told me:

“I was interested in protecting my eyes from blue light effects. Since getting Vision 20®, I notice a difference. I still use my iPad, and now my eyes don’t feel as strained.”

And Trina S., who shared:

“Before, it was very difficult driving at night. I tried to stay positive, but my eye health scared me. When I found Vision 20®, I figured it couldn’t hurt. Now I can definitely see a difference. I am much more confident driving at night.”

And Yvonne Collins, who wrote me to say:

“I had always thought vision problems were just part of getting older, but I didn’t relish the idea at all. I’ve always looked for alternative health care, so finding a product specifically for eye restoration, without any unnatural ingredients was wonderful. That, along with the professionalism of the Zenith Labs® team and the money-back guarantee convinced me to try Vision 20®.

Since starting Vision 20®, my vision has improved and my last eye test was encouraging. I even recommended it to my sister and a friend, and now they’re taking it and experiencing good results. You have nothing to lose – the product works.”

The only way for you to support our eyesight and your freedom like Frank, Trina, and Yvonne… is to try Vision 20® for yourself.

Like I said, you won’t have to worry about whether you made the right decision, because you’ll have a full 6 months to test it out.

See for yourself that really can change your life:

Act right now to claim your 6-month supply, or whichever amount is right for you.

Making this investment in yourself is something you can be proud of.

Men & women who join the Zenith Labs® family are a special group who DON’T sit around and take what life throws at them.

They don’t put up with aches and ailments just because someone says “it’s part of getting older.”

And because they care about themselves enough to act, members of the Zenith Labs® family enjoy health, success, and independence, no matter their age.

I’d love for you to join us, and since you’ve shown commitment to yourself by sticking with me through this letter, I believe you’ll fit right in.

Now I want to be frank with you…

Please don’t be offended – I’m only saying this because I want to see you healthy, happy, and confident.

But it’s time to step forward and make your decision.

And I’m asking you, as a personal favor…

Please don’t ignore everything we’ve just discussed.

Imagine what that would be like, if you turned your back and walked away right now:

You’ll still be anxious about your declining vision. Frustrated about how well you can see when you drive. Your loved ones will worry about and maybe even judge you.

The very people you should be taking care of or giving advice to, they’re the ones acting like you’re a burden to them and to society.

And worst of all, every second of every day, there’s the nagging reminder in the back of your head that your vision is only going to get worse.

There’s no escaping it.

Your near-vision, distance-vision, and night-vision will fade and blur.

But what I’m really worried about is: how you see yourself.

When the world sees you as old, past-your-prime, and a burden…

…it’s tough not to see yourself that way.

Right now, you may think, “I’ll always be active and independent.”

But the more you hear from the world that you can’t be… the harder it will get to still believe in yourself.

I don’t want you to end up sad, timid, and worried that the prime of your life is over.

I don’t want you to change your mind down the road, think about this presentation, and wish you’d taken action. Especially because this offer likely won’t be available then.

I don’t want you to regret that you decided against such a simple, small investment in yourself… an investment with huge rewards.

So please, take charge of your health & happiness – click below to claim your complete supply of Vision 20® and start your journey.

When you do, you’ll be taking your first step towards a better life.

I want you to picture that life now. I mean it – try to really imagine:

When you make the decision to protect your vision health, the day will feel a little brighter.

You’ll better enjoy your time watching TV or reading a good book, since you’ll see more clearly.

You’ll confidently wave to friends or family from across the room, and be able to see their expressions and better follow a conversation.

You’ll be more confident driving, even at night.

Those worries about losing your independence will melt away. Fears that people don’t respect you will melt away.

You’ll be confident that you can keep caring for yourself, and keep playing the same essential, helpful roles that you have for years.

Coworkers still respect you. Your children still come to you for advice. No one’s acting like you need to be coddled or taken care of.

You’re a father, mother, uncle, or aunt… maybe a manager, or a coworker, or an important player in your community.

That’s who you are, and you DON’T have to let vision decline take that away from you.

That’s why I’m asking you to try Vision 20®

Because you don’t have to roll over and accept vision decline. You’re still the active, happy person you’ve always been, and you can’t give in and let fading eyesight change that.

So one more time, I’ll invite you to click below to claim your 6-month supply of Vision 20®.

There’s no risk, since with Zenith Labs®’ “Open Bottle Guarantee,” you’ve got 6 full months to test it out for yourself, and either love the results, or get a 100% refund.

But try it now, because remember, our supplies stay low since marigold extract is in such high demand. I recommend choosing the full 6-month supply to stock up.

Vision 20® is the only way to get the purest, most effective lutein & zeaxanthin, along with our unique ingredient blends.

Click below right now, and take the first step towards reclaiming your eyesight, and staying your same happy, independent self.

I’m Dr. Ryan Shelton, and I want to say “thank you” for sticking with me through this presentation.

If you’re still here, that tells me two things:

1. You’re committed to your health and happiness, and…

2. You still have a few questions.

It’s okay to have questions. I’m glad you do, so I can help you feel perfectly comfortable trying out Vision 20® for yourself.

Here are the answers to a few of the most common questions we hear:

Will Vision 20® work for me?

Since we’ve designed Vision 20® to tackle a primary cause of vision decline – ROS Toxins – we know it will support your vision health. All the ingredients are backed by scientific studies, they’ve been used by people around the world, and I’ve personally seen them help my patients protect their vision.

Of course, not every supplement will work for every person. Everyone’s body chemistry is different. So remember, if for any reason you’re not satisfied, or even for no reason at all, we offer a 6-Month, No-Questions-Asked, Money-Back Guarantee.

Is Vision 20® safe?

I already shared with you all the safety standards that Zenith Labs® sticks to when manufacturing Vision 20®. That’s to make sure that what you see on the label is exactly what’s in the bottle — nothing more, nothing less.

Each of the ingredients that goes into Vision 20® is tested for purity and to ensure against toxins and contaminants.

We also focus on using natural ingredients, which your body already knows how to use, and which gently, naturally support your body’s natural fat-loss systems.

We still recommend that you talk to your doctor before starting any new health program, including taking Vision 20®.

Is Vision 20® a replacement for any sort of medicine or medical prescription?

No. While Vision 20® supports your health in a variety of ways, it does not treat any disease, and it does not replace any medicines you might be taking.

Use Vision 20® to support healthy vision, but always follow your doctor’s advice on any health issue.

Will Vision 20® let me stop wearing glasses?

Vision 20® is not a replacement for any prescription. Studies have shown that these ingredients support vision health, including eyesight strength, but you should rely on your doctor’s advice before making any changes to your glasses or contact lenses.

If you’re still wondering whether Vision 20® is right for you, then the best advice I can give you is to try it for yourself.

With our No-Questions-Asked, Money-Back Guarantee, you have 6 Months to see if you like it. If you decide you want your money back, simply contact us for a full refund.

So you can try it out with ZERO RISK.

You’ve got nothing to lose, and a joyful confidence to gain.

One final customer story before I let you go…

Maria Vallejos from Hawaii said, “I’ve been taking for almost 2 months and I can tell you that it is helping me a lot. So far, I have ordered three bottles and as soon as I finish, I will be purchasing again.”

Now if you’ve decided which amount is right for you, then click below, and let’s take the first step to supporting your eyesight, your independence, and your confidence.

I’ll see you on the next page.
